Geek of the Week: Sam's Club - Scan & Go

If you're a member of Sam's Club, you know the hell of standing in line with a cart full of groceries waiting for the people in front of you to check through their cart full of groceries.

Well, not any more! The price club recently released the Scan & Go app! As you put items in your cart, you scan them with your smart phone. When you're finished shopping, click the checkout button, pay for your items and go directly to the door. The checker scans the barcode on your screen, your receipt appears on their hand-held device, when they give your cart the OK, it registers on your phone and you're free to walk to your car.

A few things to keep in mind:

First – you have to enter your credit card information into the app. If that makes you nervous, you're welcome to continue standing in line.

Second – Your cart will be a more closely scrutinized as checkers compare the receipt on their device to the contents of your cart.

Finally – This is a new program, so the folks at the door, checking receipts are, more than likely, as new to this app as you are, so be patient.
